[CE17] Copy - or move - cell with items (properties)

I have (shared) cells with items. (That may be Title Block or any object symbology) The properties "belong" to that cell (they are attached to it). So you would expect (?) that when you move or copy the cell the item texts go along. 

But no they are not... Why??? (You would need to collect them before you do move or copy) see this video

If i do the very same thing (plain and simple copy) in aC it works as expected. (the very same Block shared cell is copied just fine) Even without collecting the properties.

Moreover:

If do a copy-and-paste of a block (I like to copy my titleblock to another file) This works fine in aC. But if I try this in microstation all the field information is lost.

This not only happens with DWGs It is the same in DGNs.
